FLASHING.

Specification of Letters Patent.

Patented Dec. 11, 1917.

Application filed April 16, 191?. Serial No. 162,305.

This invention relates tofiashings or roof collars intended to make a close joint between a roof and a pipe passing through the same. The object of the invention is to provide an improved flashing with which a cold joint can be effectively made, and adapted for use under conditions where different angles exist between the roof and the ipe.

The invention is illustrate in the accompanying drawing in which Figure lis a vertical sectional view of the flashing. Fig. 2 is a similar view of the flashing ring. Fig. 3 is a similar view showing the manner of applying the flashing, before ,the joint is closed. Fig. 4 is a plan view of the flashing as seen looking vertically from above. Fig. 5 is a plan view of the flashing ring as seen at right angle to its plane.

Referring specifically to the drawings, 6 indicates the rafters, 7 the boards and 8 the shingles of a roof, and 9 a pipe passing through the same.

The flashing comprises a rin 10 and a sheet lead plate 11, the ring being conveniently made of cast metal. Its opening is oval in plan, as shown in Fig. 5, to accommodate the obliqueness of the pipe with respect to the rod. The inner face of the ring is formed with a shoulder 12 extending around the same, and this shoulder may be interrupted by notches 13. The base of the ring is preferably flat where it fits against the roof board, and the upper surface is preferably rounded. The ring fits around the opening in the sheet 11, the margin of which is pressed to close contact over the upper and inner surface of the ring ,and against or upon the shoulder 12 therein,"and is also pressed into the notches 13', whereby the sheet and ring'are held together and prevented from relative movement.

The flashingds also supplied or provided with a lead cuff 14 which fits within the opening aiid closes the joint between the pipe and the adjacent surface of the ring. This lead cult is preferably supplied'in the shape.

shown in Fig. 3. That is, its edges are inclined or beveled ofl as indicated at 15. The purpose of this is to permit the flashing to assume the angle to the roof required by local conditions. That is, the cuff will accommodate or may be fitted on pipes at different angles. After the flashing and cufl are fitted to the pipe the joint is closed by hammering or tamping down the lead cuff to tight contact all around, as shown in- Fig. 1, thereby effectively closing the joint betWeen the pipe and the margin of the lead sheet where it is folded over the inner wall of the ring. The construction described allows considerable adjustment in fitting the flashing in place, and will be found very convenient and effective for the intended purpose.

.I claim:

I. A flashing comprising a ring having a flat bottom adapted to rest upon a roof and a raised upper edge adapted to project above the upper surface of the roof, a sheet of ductile metal covering said ring and projecting at its outer margin beyond the outer edge of the ring, in position to lap the adjacent roofing material, the sheet having an opening and the margin of the sheet around said opening being bent over within the ring, and adapted to fit around a pipe, and a cuff of ductile metal adapted to be tamped between the pipe and the adjacent margin of the sheet.

2. A flashing comprising a ring having an internal shoulder around the same and notches in said shoulder, and a ductile sheet metal plate overlying said ring and pressed down within the same against said shoulder and into said notches.

3. A flashing comprising a ring, having a flat bottom adapted to rest upon a roof and support a pipe, a sheet metal plate having an opening the margin of which overlies said ring and is pressed down within the same, and-adapted to fit around a pipe, and a cuff of ductile metal adapted to be tamped between the pipe and the adjacent margin of the plate, said cud having a beveled edge to accommodate pipes at various angles.

In testimony whereof, I do aflix my signature in presence of two witnesses.
